I’m simply trying to find out how long Sketchup 2016 will continue to run in a classroom lab environment if one of the workstations is upgraded to Sketchup 2017. Ij’m told that last year when we upgraded a user to 2016, all of the 2015 installs stopped working after a certain time period. I have an instructor that is wanting to be upgraded to 2017 but am hesitant to do this if 2016 will then stop working.
Network licenses are for one version only , if your maintenance contract is active, you should have received an email with latest serials and autorisation code. BUT : hardware requirements for version 2017 are higher than previous versions, test these on the workstation with the lowest specs (graphic card!)

I was under the assumption that instructor licenses were free and separate from the student lab licenses ?
Regardless you might be able to take the instructor’s machine out of the equation, by removing it’s 2016 license. From the SketchUp menu: Help > License… > (License tab of Welcome dialog) > Remove License… (button)
… but yes to be sure, get direct advice from SketchUp Technical Support (link at bottom of links below.)
